FA100 Projector Lens for 6 Optoma Installation Projectors: ZU1900 ZU1700 ZU2200 MEU962 CUL20K CUL25K

FA100 is a medium-to-long-throw lens for engineering projectors (Optoma). It is compatible with 6 models across 1 model series. This guide presents the lens specifications, installation distance, model compatibility list, and key replacement considerations in one place.

I. Lens Specifications

II. Installation Distance

The throw ratio for this model has not yet been added to our database. For installation distance, refer to the nameplate on the physical product and the user manual, or contact us to calculate it based on on-site dimensions.

III. Compatible Models (6 Models, Optoma)

The table below is arranged by model production date, from newest to oldest, and includes each model's resolution, brightness, and zoom ratio for the original factory lens, enabling quick selection according to project requirements.

The zoom ratio is the zoom factor of the model's original standard lens (upper limit ÷ lower limit of the original throw ratio range), not the zoom range of the lens described in this article.

Original Factory Interchangeable Lens Models

All 6 models can be fitted with original factory lenses. The throw ratio for each lens model is shown below for comparison with original factory solutions.

Common Features of These Models

The original standard lenses for the 6 models generally have throw ratios centered around 1.5-2.0:1. The FA100 effectively adjusts the focal range, allowing different image sizes from the same projection distance—this is the practical reason for replacing the lens. It also retains full lens-shift capability, so the image can still be aligned after the focal range is adjusted.

IV. Three Checks Before Replacement

• Verify the panel dimensions. The panel specifications for this model have not yet been added to our database. Please send us a photo of the projector's nameplate for confirmation.
• Check the interfaces and locking mechanism. Interfaces are generally compatible across platforms of the same generation, but the positions of the locking clips vary by generation. If the image appears skewed or the edges appear soft after installation, the most common cause is incomplete engagement of the locking mechanism, rather than an issue with the lens itself.
• A fixed-focus lens provides no zoom margin. Image size can only be changed by moving the projector, so site dimensions must be measured accurately, with an additional 10–20 cm allowed at each endpoint.

For models not listed in the compatibility list, it is safer to send us photos of the projector's nameplate and original lens for verification—platforms of the same generation often share the same interfaces, but ordering based only on a similar model designation carries unnecessary risk.
